摘要：

A total of 508 possible mutants affecting self-incompatibility in Phalaris coerulescens were obtained from a mutant trap experiment. None of these 'mutants', included mutations to a new functional incompatibility allele and 356 behaved as revertants. One hundred and fifty-two of the mutants were self-compatible and the methods of analysis of these mutants are described and the results from studying 37 of them are reported. Sixteen are mutants of the S locus including pollen-only mutants and one complete mutant; six are pollen-only mutants at the Z locus and 16 are mutants at a further locus T. This locus does not act to provide genetic diversity in specifying the incompatibility status of the pollen or style. Possible roles for this locus are suggested.
